They don’t typically test prototypes like this for minor revisions. I’m not sure what changes they could be doing to the Street Triple that would require a prototype. My guess is that it’s not a Street Triple at all. It’s either a very well disguised Speed Triple, which I highly doubt, or they’re testing the Daytona 765 motor in a Street Triple chassis so no one knows what it is.

It's the Euro V bike; it is a Street Triple in base trim, it will look like a facelift of the current model but extensive revisions to the electronics to homologate it, thus the prototypes are required.

Yes apparently it is the Euro 5 model with minor cosmetic changes. Thanks to the Euro5 standard it is also going to be heavier (+6kg).

"The most powerful version in the current range, the RS (pictured above) makes 121.2bhp (90.4kW) at 11,750rpm. Next yearís Street Triple RS is type-approved at a near-identical 121.4bhp (90.5kW) at the same revs, which is impressive given the cleaner exhaust emissions. The bikeís dimensions are virtually unchanged but weight increases by 6kg from 181kg to 187kg in ready-to-ride form including a full tank of fuel.
